Control menu on posts page

I’ve got Page Specific menus working just fine on the pages of the site I’m building for someone here:https://crystalwisdom.org/
but if you go to the “Blog” page which I have designated as the posts page, all the possible menus items are showing as soon as you click a post. I only want the menu items that are present on the Blog page to show when viewing posts.

Help please ?? !
